JOSEPH VALE AND CHARLES L. VALE, OF CHICAGO, ILLINOIS.

BAKERS OVEN.

Specification forming part of Letters Patent No. 104,083, dated June 7,1870.

We, J OSEPH VALE and CHARLES L. VALE, of Chicago, in the county of Cookand State of Illinois, have invented a new and useful Improvement inOvens, of which the following is a specification, reference being had tothe accompanying drawing.

The Object and Nature of the Invention.

The first part of the invention relates to the shelves so suspended fromendless chains as to remain the same side up while the endless chainsare carried on wheels, as hereafter fully described.

The object of suspending the baking-shelves directly from the chains,and having the chains pass over wheels, as described, is to build theoven in the least possible space, giving it additional height and lessground-room; and also a narrow, tall, or high chamber cooks moreeconomically when the heat is admitted at the bottom of it than a wideand low chamber and our invention also relates to the arrangement of thetwo or more doors in the oven, so that it can be operated from eitherfloor of the building, or the oven can be fed from one floor of thebuilding and its baked contents removed through the door on anotherfloor.

Description of the Drawing.

Figure 1 represents a front elevation of our oven; Fig. 2, an endelevation; Fig. 3, a sectional view at the line aa; Fig. 4, a sectionalview at the line y 3 General Description.

then elevating to another floor for packing, as.

is usually the case. There are two shafts, F, across the interior of theoven, on each of which there are two wheels, H, with teeth or cogs ontheir periphery, as shown.

I are endless chains, made sufficiently long to extend over one of thewheels on each shaft, and they are revolved with the wheels as they areturned by means of the teeth thereon. One of the shafts F extendsthrough the wall of the oven, and has a crank, J, or pulley on it, bywhich it is driven.

K are shelves suspended on arms L, that have bearings in the chains I,on which they turn as the chains are carried around on the wheels, sothat the shelves remain suspended the same side up the entire revolutionthrough the oven.

By hanging the shelves K on the chains I they can operate in an ovenonly twice the width of each shelf, that width giving sufficient spacefor the shelves to pass each other as they pass over the wheels.

In making the ovens, however, we usually allow a little space, so thatthe heat will pass up among the shelves without interruption.

Frequently in cities it is desirable to build ovens for baking on narrowlots of ground, and an oven that can be built narrow and high is verydesirable; and as the heat has a tendency to rise, a high. narrow ovenwill retain the heat better than a low broad one.

It will also be observed that the shelves are carried through all partsof the oven, so that the baking will be done evenly on all the shelvesalike.

O is the furnace, extending across the oven, with a door, P, foradmitting fuel at each end. Q are the fire-grates. It are the doors tothe ash-pit beneath the grates. S are fines opening directly into theoven, and T is the smoke pipe or flue.

Ola int.

What we claim, and desire to secure by Letters Patent, is-

The shelves K, chains I, and wheels H, when the shelves are suspended onthe chains, the axis of their suspension being at the periphery of thewheels, and all are constructed and operating in an oven, substantiallyas and for the purposes specified and shown.
